(a) pT = 13/20 = 0.65
pN = 5/20 = 0.25
pT - pN = 0.65 - 0.25 = 0.4
(b) The hypothesis being tested is:
H0: p1 = p2
Ha: p1 > p2
(c) z = 0.4/0.154 = 2.60
p-value = 0.0047
Since the p-value (0.0047) is less than the significance level (0.05), we can reject the null hypothesis.
(d) Therefore, we can conclude that people receiving cognitive behavioral therapy experience greater sleep improvements than those who do not receive therapy.
